'Execution' in the Bible

On the night before Herod was to bring him out for execution, Peter, bound with two chains, was sleeping between two soldiers, while the sentries in front of the door guarded the prison.

After Herod had searched and did not find him, he interrogated the guards and ordered their execution. Then Herod went down from Judea to Caesarea and stayed there.

But having received information of a plot about to be put in execution against the man by the Jews, I have immediately sent him to thee, commanding also his accusers to say before thee the things that are against him. Farewell.
